3 Claims. (CI. lea-146.5)

This invention relates to ozonators, and it has more particularly to do with the installation of a device of this character within the closed body of an automobile, motor bus or the like. The invention further relates more particularly to that class of apparatus in which the ozone is produced from atmospheric air by the silent discharge of I high potential electricity.

It is one of our objects to provide a new and improved form and arrangement of parts comprising an ozonator connected up with the ignition system of a gasoline engine so as to pro vide for effective operation of the ozonator by the use of a minimum of parts in addition to the'usual ignition system apparatus. To this end, it is one of our objects to provide an improved arrangement by which the means for causing intermittent flow of current through the primary winding of the ignition coil is utilized also for causing intermittent flow ofcurren't through the primary winding of another coil, by the secondary winding of which other coil high potential surges of current are impressed upon an ozone generator.

The invention consists also in the apparatus andin the parts and combinations and arrangements of parts thereof as hereinafter more fully described and pointed out with particularity in the appended claims.

In the accompanying drawing, illustrating an adaptation of the invention, f

"Fig. 1 is a side elevation of an automobile of the ordinary closed body type, thearrangement of the ozonator and the cooperating circuits and working parts being shown in dotted lines; and

Fig. 2 is a diagram showing a practical layout of the different parts of the apparatus and the electrical connections between them.

-Referring now to the drawing, the numeral 5 designates generally the body of an ordinary automobile. The ozonator or. generator itself, which may be of any approved or desirable type, is designated generally by the numeral 6 in both Figures 1 and 2, as shown, it is located in the top portion of the automobile body but, obviously, it may be ocated in any other convenient .place therein. Preferably, the generator structure is of a very simple and inexpensive type. In'the diagram in Fig. 2 it is merely represented by two separated field plates 7 comprising'a condenser,

the usual central dielectric plate and other structural parts being omitted, as the particular struc-. tural features of the generator are not concerned in the present invention.

The usual electric battery with which the car is equipped is indicated by-the numeral 8 in both through the wire 19. coil .18 is connected to a wire 23, which latter is also connected to the coil 1'7 at the end therefigures in the drawing, the distributor or alter- .nating circuit closing and breaking device being designated generally by the numeral 9 and the ignition coil by the numeral 10.

The numeral 11 designates the usual circular distributor housing or casing having the series of electrical terminalelements 12 located there on and spaced thereabout in annular series, said elements being respectively connected by wires 13 to the spark plugs 14, of which there are six indicated in the diagram in Fig. 2; one of them being illustrated in side elevation and in somewhat complete detail, and the other five being merely represented by conventional diagram symbols. The usual rotor which cooperates intermittently with the terminal elements 12 is designated by the numeral 15, this rotor'being connected by the high tension wire 16 to the secondary winding 17 of the ignition coil 10.

The primary winding 18. of said ignition coil 10 is connected at one end to a wire 19, which is in turn connected to one pole of the battery 8, the opposite pole of which latter is grounded through the wire 20. In the wire 19 is the usual circuit breaker or switch 21 for opening and closing the ignition circuit at will, and, for the purpose of the present invention, the wire 19 is provided with a second circuit breaker or switch 22, which latter may be termed the ozonator switch for the reason that it is specially provided for controlling the ozonator. Normally, when said second mentioned switch 22 is closed, and provided, of

course, the switch 21 is also closed, the current from the battery 8 passes directly to the coil 18 The opposite end of the of, opposite to that'which is connected tothe wire 16; The wire 23 is connected also to a -of engagement with the terminal contact 24. It

is adapted to be intermittently actuated to bring said members 24 and 26 into engagement by the action of a polygonal element 28 which rotates about the axisof the member ,15 in normal engagement with a roller 29 at the end of said pivoted member 25. Said member 25 is grounded through the wire 30 so that when contact is through the primary coil 18 and also through the secondary coil 17.

The electrical parts and circuits thus far described constitute the usual or ordinary ignition system of an automobile or the like. In operation, as the rotor and polygonal member 28 rotate in unison, the induced relatively high tension current from the winding '17 is conducted intermittently to the respective spark plugs 14 through the wires 13 and 16 as the member 15 moves into cooperative relation to the respective terminal contacts 12. At the same time, the member 28 acts upon the roller 29 to actuate .the pivoted member so as to bring the contact 26 into engagement with the contact element 24 just after the member 15 moves into co--' operative relation to the terminal element 12, the engagement between said parts 26 and 24 being broken just prior to the movement of the member 15 out of cooperative range of the terminal element 12. While the contact members 24 and 26 are in engagement thecurrent is passing from .the battery 8 through the wire 19, primary coil 18 and circuit wire 23, and the ground wire 30.

At one side of the cirauit breaker or switch 22 the wire 19 is extended, as at 31, and connected to one end of the primary winding 32 of a coil 33, which may be termed the ozonator coil, 'the opposite end of the primary winding 32 being connected by a wire 34 to the wire 19 at some point between the two switches 21 and 22. The wire 34 is also connected, as at 35, to one end of the secondary winding38 01' said ozonator coil 33, the opposite end of said winding 36 being connected by the wire 37 to one oi. the plates 7 or the ozonator 6, the opposite plate of said ozonatorbeing grounded through the wire 38.

The winding 32 of the ozonator coil 33 is of lower resistance than the winding 18 of the ig-' nition coil 10. Consequently'the regular bat-- tery 8, which is usually provided for the ignition system, may be utilized for the dual purpose of providing the electrical energy for the ozonator, as well as the ignition system, and, obviously,

, without detracting appreciably from the proper operation of the ignition device or decreasing the efliciency thereof. By this manner of installing the ozonator-in the automobile or other vehicle having an ignition system or thelike, the operation 01' the distributor mechanism to intermittent 1y close and break the circuit sequentially for the respective spark plugs or ignition devices, serves also to produce the required surges of high potential current through the secondary winding 36 for impression on the condenser 6.

Normally, when it is not desired to operate the ozonator, the switch 22 is closed and the ig- 3 nition system is rendered operative by the closing of the switch 21 in the usual manner, the switch 22 and'its lead serving as a by-pass connection around theprimary winding 32. When it is desired to operate the ozonator it is only necessary to open the switch 22, whereupon the ozonator circuit is effectively in series with the ignition ever, the invention is not'to be limited in its.

application to a motor car in operative connection with the ignition system alone, as the ozonator may beinstalled in the car in connection with made between the members 24 and 2G, and the switches 21 and 22 are closed, current is passed some regular equipment having characteristic cooperating elements which may take the place of the distributor mechanism 0! the ignition system to obviate the necessity for specially providing separate devices for this purpose.

Obviously, many modifications and changes may be made in the construction and arrangement of the parts and in the manner of installation thereof without in the least departing from the spirit and scope of the invention as set forth in the appended claims.

The invention, therefore, is not limited to the specific construction and arrangement shown in the accompanying drawing.

Having thus described ourinvention, what weclaim as new and desire to secure by Letters Patent is:
